2 Claims.

My present invention is directed to improved valves for outlets of receptacles and operating mechanism therefor. 7

An essential of the invention resides in a valve be equipped with a valve member and operating mechanism therefor, whereby the valve member is movedtoward and to its closing position in a direction transversely of the direction of opening of the outlet of the receptacle. Such relationship of the movable valve member afiords a selfcleaning action relative to the opening, in that the closing movement of the movable valve member insures the removal of any lint, soap residue, surface accumulation, etc., incident to use of the tub or other receptacle.

In the preferred forms of my invention, the 'movable valve member comprises a plate portion, which may be substantially flat, the effective faces of theoutlet being substantially flat, and g0 appurtenant elements associated with the plate I portion of the movable valve member for increasing the degree of frictional engagement of "the same with the effective faces of the outlet as the valve member is moved toward its closed 25 position.

In the more preferred forms of my invention the plateportion of 'the movable valve member is provided with wedge or cam-like flanges cooperating with guide means havingslots of cor- 30 responding wedge or cam contour, such guide means terminating at a, location anterior of the position of the valve member'when in its closed position, thus affording a clearance in the guide means beyond its stated termination, thus en- 35 'abling the movable valve 'member to project through such clearance, for compensation of wear, varied degree of friction between the movable valve member and the faces of the outlet, and other self-compensating purposes.

40' Fig. 1 is' a detail vertical section of a tub equipped with a preferred form of my invention.

2-is a sectional elevation on line 22 of f Fig. 3 is asectional elevation on line 3-4! of 45 Fig. 1.

Figsfl is a detail elevation as viewed from line t-@ of Fig. 3, r r V Referring to Figs. 1, 2, 3 and 4 of the drawings, the embodiment is exemplified as a control valve for a tub I!) having a bottom outtake H and an overflow outtake l2.

Thetub indicated the drawings is repre- .sentative of other types of receptacles, particu- 55 larly having an overflow discharge, such as lavatories, laundry tubs, sinks, industrial and other tanks, etc.

In the embodiment shown in Figs, 1, 2 and 3 the outtake H is shown disposed to have its lower edge coincident with the face of the bottom la 5 of the receptacle ID, the axis of the opening I extending substantially horizontally, thus affording drainage to a maximum of the receptacle ID in a horizontal direction.

A strainer plate I3 is preferably provided for the bottom outtake H, and also preferably located within the receptacle l0, whereby any articles and/or foreign matter are readily accessible.

The control valve embodied in my invention, as shown in Figs. 1, 2 and 3, embodies a movable valve member I4 suitably mounted in proper guide means with respect to the effective discharge opening of the receptacle, in this instance the discharge opening of the nipple l6, suitably connected for communication with the discharge opening H of the receptacle Ill. Such movable valve member I4 is illustrated as having an effective closure in the form of a plate and coordinated with suitable operating means, gen- 5 erally designated l1, provided with an accessible handle l8.

Advantagecusly, the nipple I6 is unitarily mounted in coaction with the strainer plate |3 on opposing sides of the rim of the outtake ll, as by means of a set screw I9 the stem of which passes through a suitable opening [3a, see Fig. 4, of the strainer plate l3, and a spider element 20 having its central boss tapped to receive the thread of the set screw, I9.

Preferably, the guide means, see 2|, 2|, Fig. 2, and the movable valve member M are related in wedge-like or cam-like manner to one another, whereby upon closing movement of the movable valve member l4 theeffective face of the same is brought in increasing frictional relation with the rim edges of the outtake ll.

The movement of thetmovable valve member I4 is preferably ina general vertical plane, thus enabling the nipple I6 and the effective opening I5 of the receptacle to be also located to have a horizontally directed outflow.

- Specifically, the member M has flanges [4a, extending rearwardly at its opposite vertical edges relative to the effective face of its closure plate, which flanges Ma are-of wedge formation and taper downwardly, and the guide means 2|, 2|, for the respective flanges Ma have open sided slots which taperdownwardly.

The movable valve member l4 and its handleinterconnecting linkage l'l are advantageously disposed within the outflow passage means of the overflow opening l2 of the receptacle; such arrangement affords locating the operating shaft 22 of the handle I8to pass through an opening in the body of the strainer plate 23 of the overflow opening [2, to thus serve as a bearing.

The passage means of the overflow opening is shown in the form of a series of successively connected tube lengths 2 extending from the mouth of the overflow l2 to the trapway 25, thus serving as a common discharge for-the bottom opening it and overflow opening l2. Such tube'lengths are advantageously screw-threadedly related to one another and to the nipple l6, which may also be of screw-threaded component parts, and screw-threadedly related to the strainer plate 23 of the overflow opening 52; in such instance, the strainer plate may have a cylindrical flange 2341, the peripheral projecting end of which is threaded for-threaded connection with the rim 24a of the uppermost, i. e., elbow section 24. A gasket 25 is advantageously interposed between the rim 25a and the flange 23a 'jointly with the edge of the overflow opening l2. Gaskets are provided for at the respective screw threaded joints, as indicated in the drawings.

The linkage between the shaft 22 and the movablevalve member M may be of any suitable character. Conveniently, cam actuation desir-- able for-such form of linkage is had by bending the free end 22a of the. shaft and pivotally connecting thereto a link 26, secured by a cotter pin connection indicated at 21, and provided an eye or equivalent 26a at the lower end of the link for pivotal connection with a stud 28 secured to the back of the movable valve plate l4, secured, say, by a cotter pin connection indicated at 291. Accordingly, upon rotation of the handle i8 and the body of its shaft 22, its cam end 22a effects the raising of the link 26, thereby raising the movable valve member H5 in its guide members 2|, 2|,

. whereby the efiective discharge opening I5 of the receptacle in is moved to its full open position.

The dot and dash outline Ila indicates the maximum upward position of the linkage I! and the dot and dash outline of the movable valve member Ma indicates its uppermost position, at which position the opening I 5 of the receptacle [0 is wholly open. In such fully open position, the linkage, and therewith the closure member, are held automatically by the stated cam' formation and bend II-a of the link 26.

The. trapway 25 is connected to any suitable soil or waste piping of a plumbing system, embodying proper venting of the stated parts.

An essential advantage attained by the inventionresides in the"shearing action effected by the stated movable valve member relative to the edgesof the discharge opening, thus automatifca'lly clearing the discharge opening of all obstruction.

"The above or equivalent arrangement results -.,in closure means for a receptacle wherein wear of the parts incident to use is automatically compensated. Such advantage results from the Wedge-like or cam-like relationship of the movable valve member comprising a plate for- 'mation and the co-action therewith of appromovable valve member and a correspondingly tapered guide therefor. Such relationship is further enhanced in the illustrated embodiment by terminating the lowermost edges 2Ib, see Fig. 2,

of the guide means at a location above the lower edge of the discharge opening.

The invention offers the further advantage that the movable valve member and its handle-interconnecting linkage are disposed in zones which are not fouled incident in the use of the receptacle, that is to say, the movable valve member Hi, the linkage IT and the operating shaft 22 are located within the passage means 24 which during the stage of open position of the movable valve member is fully aerated as well as being concealed, I y 1 The particular assembly of the movable valve 22, inclusive of its cam end formation 22a, affords the mounting of the shaft 22 and therewith the handle l8 through the overflow opening l2 of the receptacle, and further enables the stated parts to be readily withdrawn through the overflow opening 42 for inspection'and/or repair. From the above, it is apparent that the movement of the movable valve member toward and to its closed position effects a shearing of the faces of the outlet by the plate portion of the movable valve member. I An effective assembly is had by a substantially flat plate portion of the movable element and substantially uni-planar faces of the outlet, whereby the movement of the movable valvemember provides for such shearing action over an appreciable extent of movement of the valve member toward its closed position. For simplicity of assembly and disassembly, the'pivotal connection, see eye26a, receiving the stud 28 and cotter pin connection 29, may have considerable lost motionfiand at the same time insure a full seating of the plate portion with respect to the faces of the outlet with the movable valve member when moved to its closed position, and irrespective of the wear of the stated parts.

1. In combination with a receptacle having a lowerly disposed outlet with its lower edge coincident with the face of' the bottom of the receptacle and an upwardly disposed outlet, valve means for the lowerly disposed outlet, said lowerly disposed outlet having a face about its opening of substantially 'uniplanar formation, said valve means including a" member having a substantially uniplanar face portion for 'co-actio'n with the uniplanar face portionof the lowerly disposed outlet, guide means cooperating with said movable valve member, operating linkage extending through the upwardly disposed outlet of the receptacle for movingsaid valve member to and from its closedposition, andpassage vmeans communicatively connecting the upward- 'ly disposed outlet and the lowerly disposed outlet with a common discharge, said passage means serving to house said linkage and said movable -'cident with the face of the bottom of the 'recep tacle, and an upwardly disposed outlet, valve means for the lowerly disposed outlet, said lowerly disposed outlet having a face about its opening of substantially uniplanar', formation, said valve means including a member having a substantially uniplanar face portion for co-action' -member, its linkage I] and its operating shaft a common discharge, said passage means serving to house said linkage and said movable valve member, and a strainer plate for said lowerly disposed outlet located within said receptacle whereby any articles of foreign matter within 5 the said outlet are readily accessible for removal.
